newsoobdude Posted October 27, 2007 Share Posted October 27, 2007 This is a stupid newb question I'm sure, but is there a difference between between the 1800cc intake manifolds through the years, particularly 1983 and 1985/ 86 Brats? I'm going to be switching to an EA82 IM for more performance (among other mods) but would like to know so I can see vacuum hose "ports" and what not before I take my 86 apart. Also, does anyone have the vacuum diagrams for an EA81 and 82? Thanks. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 27, 2007 Share Posted October 27, 2007 Not really, except for the obvious differences between the Hitachi and Carter/Weber manifolds. If you are using an EA82 manifold, then you will want a Weber so vacuum routing won't matter. The EA82 Hitachi is crap - worse than the EA81 version in several ways. Don't go there. Better yet - go with the SPFI conversion. GD Quote Link to comment Share on other sites More sharing options...

The EA82 Hitachi would be the LAST carb I'd choose to put on it, I'd like to keep the OEM EA81 until I go SPFI. As for a Weber, it'd be nice but I need it to pass the dreaded Cali SMOG Nazi's , hence the vacuum diagrams. Quote Link to comment Share on other sites More sharing options...

You can trick the smog guys by cutting out a stock airbox and putting it on the Weber. GD Quote Link to comment Share on other sites More sharing options...
